目的:本研究检查了自制牛心包管移植物在所有解剖部位的主动脉感染中的结局和耐久性。
方法:这是一项回顾性和前瞻性的国际多中心研究。分析了2008年1月至2020年12月在四个欧洲三级转诊中心进行主动脉原位重建治疗自体牛心包管移植物或移植物感染的患者的围手术期和长期结局。主要终点为复发性主动脉感染。次要终点是持续性感染,主动脉再手术治疗感染,移植物相关并发症,和死亡率。
结果:一百六十八个病人(77%为男性,平均年龄67±11岁):38例(23%)与天然和130例(77%)与主动脉移植物感染。30天死亡率为15%(n=26),11%(n=4),17%(n=22)用于天然和主动脉移植物感染,分别(p=.45)。中位随访时间为26个月(四分位距[IQR]10,51)。估计存活率为1,两个,三,五年是64%,60%,57%,50%,对于本地人来说明显更好(81%,77%,77%,和69%)比移植物感染(58%,55%,51%,和44%;p=.011)。9例患者(5.3%)持续感染,10例患者(6%)在中位10个月后发生主动脉再感染(IQR5,22),导致估计一次免于再感染,两个,三,五年的94%,92%,90%,和86%。估计无移植并发症,两个,三,五年是91%,89%,87%,和87%。
结论:这项多中心研究表明,使用自制的牛心包移植物时,再感染率较低,与其他生物移植物相当。移植物并发症的发生率,主要是吻合动脉瘤和狭窄,很低,而没有移植物变性。自制的牛心包管移植物是在天然主动脉感染或主动脉移植物感染情况下原位重建的绝佳工具。
OBJECTIVE: This
study examines outcome and durability of physician made bovine pericardial tube grafts in aortic infections in all anatomical locations.
METHODS: This was a retrospective and prospective international multicentre
study. Peri-operative and long term outcomes of patients undergoing in situ aortic reconstruction for native or graft infections with physician made bovine pericardial tube grafts between January 2008 and December 2020 in four European tertiary referral centres were analysed. The primary endpoint was recurrent aortic infection. Secondary endpoints were persistent infection, aortic re-operation for infection, graft related complications, and death.
RESULTS: One hundred and sixty eight patients (77% male, mean age 67 ± 11 years) were identified: 38 (23%) with native and 130 (77%) with aortic graft infection. The thirty day mortality rate was 15% (n = 26) overall, 11% (n = 4), and 17% (n = 22) for native and aortic graft infections, respectively (p = .45). Median follow up was 26 months (interquartile range [IQR] 10, 51). Estimated survival at one, two, three, and five years was 64%, 60%, 57%, and 50%, and significantly better for native (81%, 77%, 77%, and 69%) than for graft infections (58%, 55%, 51%, and 44%; p = .011). Nine patients (5.3%) had persistent infection and 10 patients (6%) had aortic re-infection after a median of 10 months (IQR 5, 22), resulting in an estimated freedom from re-infection at one, two, three, and five years of 94%, 92%, 90%, and 86%. Estimated freedom from graft complications at one, two, three, and five years was 91%, 89%, 87%, and 87%.
CONCLUSIONS: This multicentre
study demonstrates low re-infection rates when using physician made bovine pericardial tube grafts, comparable to those of other biological grafts. The rate of graft complications, mainly anastomotic aneurysms and stenoses, was low, while graft degeneration was absent. Physician made bovine pericardial tube grafts are an excellent tool for in situ reconstruction in the setting of native aortic infection or aortic graft infection.
